BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the field of waste removal containersand more particularly to collapsible waste removal containers for use atconstruction sites, commercial sites, industrial waste sites, townhouses, multi-family homes and condominiums.

2. Description of the Related Art

At construction sites, such as high-rise buildings for new construction,remodeling, building refurbishment or modernization, and at industrialwaste sites, one of the problems faced by the builder, constructioncompany or business is the removal of substantial amounts of waste,debris and garbage. Conventional ways for waste, debris and garbageremoval at construction and industrial sites are accomplished bylocating multiple containers or bins at various waste collectionlocations at the construction or industrial site. Typical containers orbins are approximately twenty feet long, six to eight feet wide andthree to eight feet deep. These containers are typically referred to as“roll-off” containers and may have wheels to make the stationaryroll-off containers into mobile roll-off containers. Such roll-offcontainers usually have three standard sizes: one size is twenty cubicyards, a second size is thirty cubic yards and the other size is aboutforty cubic yards.

Since all roll-off containers have different trash weight and capacity,which is dependent upon the ability of an associated “roll-off truck” topick up the loaded containers and upon state and/or local restrictions,the size of roll-off container selected depends upon the weight of trashor other materials to be dumped therein. For example, the twenty yardroll-off containers are typically most efficiently used on constructionsites for heavy waste materials, such as broken masonry, concrete andasphalt; earth; bricks and tile. The thirty and forty yard roll-offcontainers are typically constrained to receiving lighter-weightmaterials, such as scrap lumber, plasterboard, broken shingles, treebranches and trimmings, business and household garbage and typicalpackaging waste such as corrugated cardboard, cardboard and packingmaterials. Regardless of which roll-off container is selected, theseroll-off containers are too heavy for trucks having front or rear endloaders to lift and empty the construction waste materials. Instead, anassociated “roll-off truck” will pick up the roll-off container.

Conventional roll-off containers are made as single integrated unitsconstructed of heavy materials such as metal and cannot be disassembled.As such, each roll-off container has a fixed footprint that requires aset amount of space at the construction/industrial site regardless ofwhether that roll-off container is in use or is waiting to be used. Thiscauses a problem at many construction and industrial sites that havelimited space available to place waste containers, much less store emptyroll-off containers. More importantly, as roll-off containers are singleintegrated units, the roll-off containers are typically transported oneat a time to the construction/industrial site whether empty or loadedwith debris, which squanders time, fuel, resources and money.
